Quite frankly, I don't take anything that happens '300 years later' will be canon. I think that TOR is going to run into the ground and the third KOTOR will eventually be released. When it does, it will overtake all the events of TOR and become new canon.

I am not going to trash TOR for existing, so long as it doesn't infringe upon the story of KOTOR, which still has yet to be completed.
